Specification of Letters Patent.

Patented Dec. 24, 1918.

Application filed May 10, 1918. Serial No. 233,776.

To all whom it may concern:

Be it known that I, WALTER E. LINCOLN, a citizen of the United States,residing at Belvidere, in the county fBoone and State of Illinois, haveinvented certain new and useful Improvements in Power-Generators, ofwhich the following is a specification.

The primary object of this invention is to devise simple means forgenerating fluid pressure to be subsequently expanded for driving amechanism whereby power is developed to be used for operating machineryor any other manner required in the industrial arts.

The main feature of the invention resides in a tank for receivingsuccessive charges of fluid pressure which are generated by explosionsof a gaseous mixture, the pressure thus generated being utilized foroperating a.

turbine or other type of power wheel from which motion maybe taken foroperating any part to be driven.

A further purpose of the invention is the provision of a mechanism whichcombines in a unitary structure devices for developing and utilizingpower, and means for supplying a gaseous mixture and exploding the samewhereby the expanding gases are utilized as motive power for operatingthe part to be positively driven.

The drawing illustrates a preferred embodiment of the invention,however, it is to be understood that in adapting the same to meet diflerent conditions, various changes in the form, proportion, and minordetails of construction may be resorted to without departing from thenature of the invention as claimed hereinafter.

In the drawings Figure 1 is a diagrammatic view of power generatingmeans embodying the invention, portions being broken away to show moreclearly the relation of the working parts,

Fig. 2 is a detail view of a portion of the turbineor motor wheel and aportion of the tank containing the motive medium,

Fig. 3 is a sectional detail of the driving mechanism on the line 33 ofFig. 1 showing the parts on a larger scale.

Corresponding and like parts are referred to in the followingdescription and indiwheel 3.

cated in the several views of the drawing by like reference characters.

In the drawings the letter A designates a tank for containing ahydrocarbon or liquid fuel of any nature. The reference let- ;ter Bindicates a tank for containing air under pressure, said tank being keptcharged 1n any manner. The letter C represents a carbureter and isconnected with the fuel tank A by means of a pipe 1 and with the airtank B by means of a pipe 2. These parts may have any relativearrangement found most convenient in the construction and installationof the mechanism.

nected thereto in any convenient way. A

turbine wheel 3 is located at one end of the tank and is adapted to bemounted in any manner. A portion of the tank D is depressed as indicatedat 4 so as to conform to the clrcumference of the turbine or power Thedepressed portion 4 of'the tank D has an outlet 5 through which thefluid pressure escapes in a jet so as to impact against the bucket-s orblades of the turbine and impart a rotary movement thereto.

,The outlet 5 may be of any form but it is to be understood that thesame must be so disposed as to deliver the jet in a manner to causerotation of the turbine or power wheel 3..

As indicated most clearly in Fig. 1 the chamber E is disposed exteriorto the tank D. and relatively at an acute angle thereto. The chamber E iprovided with a valve 6 by means of which the gaseous mixture isadmitted thereto. The inlet valve 6 is located at the outer end of thechamber E. A valve 7 is disposed in a side of the chamber E. andpreferably in the lower wall thereof. The valve 7 constitutes a reliefso as to provide for admission. of a charge of explosive mixture intothe chamber E. A shield 01' bafile 8 extends over the valve 7 and isdisposed in a manner to cause the incoming gaseous mixture to pass tothe lower end of the chamber without escaping through the openingcontrolled by the relief valve 7. The baflie or shield 8 is connected atits upper end to the lower wall of the chamber E at a point distantnates ashort distance from from the valve 7 and its lower end termi v Vthe lower end of the said chamber. P

.I' A cylinder '9 is located within the tank D and isconnected' atitsupper end to'the top of the tank and is openedat its lower end. Outlets"10.. are formed in the sides o'f'the cylinder 9a short distance fromthe upper end thereof. A .piston 11 -operates in the cylinder '9andnormally occupies a posl-j tion .a'tthe upper end thereof. The piston11 is held in-normal' position'by means of an expansible helical spring12 mounted on the projecting endof the stem of the piston.

The cylinder-f9 is in communication with the lower end of the chamber E.A portion of thef top of the tank D overhangs the upper end' of thecylinder 9 and constitutes a sto 13 which limits the upward movement 0the piston. Under normal conditions the piston 11 occupies a positionabove the outlets 10 hence said piston separates the chamber E from theinterior of the tank D. i

The reliefvalve 7 is adapted to be positively operated, and for thispurpose a rocker arm 14 is provided, and is. adapted to be operated froma shaft 15 by means of a link 16. A sprocket chain 17 connects asprocket wheel 18 secured on the shaft 15 with, a sprocket wheel. 19secured on the shaft of the turbine or power wheel 3. In

.this manner movement is transmitted from the turbine to the shaft 15.

The gaseous mixture is exploded by means of a spark plug 20 which isincluded in an electric ignition system the latter including a magneto21 of any type or make. A lead wire 22 connects the timer 23 of themagneto with the spark plug 20. gearing 24 is adapted to transmit powerto the magneto for driving the same. This train of gearing includes ashaft 25 to which is secured a sprocket wheel 26 the latter beingdisposed. so as to be'engaged by the upper run of the sprocket chain 17.

The parts being disposed substantially as indicated in Fig. '1 and asset forth herein the operation may be briefly stated as follows Theliquid fuel such as gasoleneis stored in the tank A and air" underpressure is contained in the tank B. Upon openingthe valve7 the airpressure from the tank B will pass into'the chamber E through the'carbureter C, and as the an passes through the carburetor it will takeup a portion of the fuel in the manner well understood so that a gaseousmixture will pass into the chamber E- through the opening controlled bythe valve 6. The parts are so timed that when the chamber E receives-aproper charge of the gaseous mixture the relief valve 7 A train of Icloses and at this instant the circuit is closed thereby producing aspark wh ch explodes been relieved of the expanding gases the valve 7 isagain opened thereby permitting the piston 13 to return to normalposition and the valve .6 to open mechanically or automatically by thepressure derived from the tank B so that the chamber E received a secondcharge which is again exploded in the manner stated.

The valve '7 is positively operated whereas the valve 6 is openedfby thepressure de rived from the tank B and C at such times when the reliefvalve 7 is open. The valve 7 is actuated eriodically and closes theinstant the cham or E received a proper charge of gaseous-mixturethereby preventing any waste of pressure or fuel. The charge deliveredinto the tank D by the expanding gases escaping thereinto passes outthrough the nozzle or outlet 5 in a jet which strikes the buckets orblades of the turbine and imparts a rotary movement thereto.

The foregoing description and the drawings have reference to what may beconsidered the preferred, or approved, form of my invention. It is to beunderstood that I may make such changes in construction and 1arrangement and combination of parts, ma-

terials, dimensions, et cetera, as may prove expedient and fall withinthe scope of the appended claims. Anextension at confines the gas andprevents waste thereof.
